These iPhone applications and games will let you glow in the dark, engage in space war with the Moon combatants, and even study for your driver's exam. Sort of.
iPhone drawing applications are the logical conclusion for iPhone developers in light of the touch screen. In a sort of finger painting the touch screen acts as the hand to phone intermediary that makes these bits of logic work. In perfect iPhone application fashion each developer of iPhone drawing applications tries to capture one quality feature that makes that particular application worth it. Perhaps it does a heat sensitive mood response. Maybe it draws out in rainbows. This one kind of glows. Glow Coloring, as the name implies, is a free iPhone drawing application that allows you to draw on the touch screen. Each streak has a subtle glow to it, hence the Glow Coloring title. You have the built in ability to take a picture of your work, import a picture to draw on, select a background to use, and of course pick from a number of glowing colors. This is all pretty standard, and if you like it, effective. You are not going to get anything new from Glow Coloring that you do not get from most iPhone drawing applications except for the minor glow you get from the streaks. It is relatively fun and you could do a lot worse, and until there are the ultimate iPhone drawing applications at the iTunes' App Store you will have to make do. Just don't hit your finger on the banner ad that crowns out the top of this free iPhone application.
One thing that just does not fly on the iPhone is loading and preparation times. The reason is that unlike console or computer gaming the iPhone requires quick on and off timing because of the sparse use of the iPhone as a gaming vessel. In this way some time Open Feint can be a hindrance, and Earth Vs. Moon reminds you of this. Once you get beyond this aspect Earth Vs. Moon is a pretty interesting and complete shooting game in the tradition of Space Invaders. You are positioned with three missile ships that you then inspire to shoot torpedos at incoming shards of debris and enemies. This all starts with the Hubbell telescope being attacked and hurdled to earth by moonanites. You must defend against this without going over your missile limit or allow them to penetrate your guard. Earth Vs. Moon has a complete story mode with tutorial and other features, all of which is impressive from a free iPhone game and becoming standard for those on the Open Feint network. The missile control can be a little awkward as you have to tap the exact position where you want them to go and hope that they hit your target, but after a few plays you begin to get the hang of it and it is both fun and challenging. This is all colored with funny little newspaper headlines that remind you that this is a space age satire. Once you do die, and you will inevitably expire at some point, it is difficult to get back into the main menu. With a few minor things aside Earth Vs. Moon is actually a solid, arcade style game for your iPhone that utilizes the touch screen in a simple and effective way.
Oh yeah, there's an app for that. That clever little bit of Apple marketing is more true than most people give it credit for. Drivers Ed is a free iPhone application that help you prepare for your driver's test. No, it does not give you a driving simulator so you can parallel park. Instead it focuses on the question and answer portion, which most people seem to hammer down when that's the only thing between them and the open teenage road. Driver's Ed actually brings a whole host of study modes such as practice tests that you can set the question number on, completed tests that you can look back over when you are finished, flash cards, your state's drivers manual in a miniature portable form, and some other "useful" bits of information about driving education. All of this is here to promote driversed.com, which is a commercial site dedicated to exactly the same features as the free iPhone application. In this way you can kind of trust the material that is in Drivers Ed, but know that all roads really just lead back to the website. Drivers Ed does deliver on what it promises, over all. It has limited appeal and is likely not the ideal way to study for your driver's exam, but maybe in the new iFuture it will be. It is somewhat sluggish and the interface leaves a little to be desired, but for its narrow purpose this really is going to be one of your best bets.
